In keyfob code, the gapRole_AdvertOffTime is set to 0 in KeyFobApp_Init();

 GAPRole_SetParameter( GAPROLE_ADVERT_OFF_TIME, sizeof( uint16 ), &gapRole_AdvertOffTime );
1

While Keyfob is set in limited discoverable mode

#define DEFAULT_DISCOVERABLE_MODE             GAP_ADTYPE_FLAGS_LIMITED
1

which will stop advertising after 180s by the following parameter

#define TGAP_LIM_ADV_TIMEOUT           1  //!< Maximum time to remain advertising, when in Limited Discoverable mode. In seconds (default 180 seconds)
1

you can change by :

GAP_SetParamValue( TGAP_LIM_ADV_TIMEOUT, xxxxx );
1

In KeyFobApp_Init(); you will find code for setting the advertising interval

  // Set advertising interval
  {
    uint16 advInt = DEFAULT_ADVERTISING_INTERVAL;

    GAP_SetParamValue( TGAP_LIM_DISC_ADV_INT_MIN, advInt );
    GAP_SetParamValue( TGAP_LIM_DISC_ADV_INT_MAX, advInt );
    GAP_SetParamValue( TGAP_GEN_DISC_ADV_INT_MIN, advInt );
    GAP_SetParamValue( TGAP_GEN_DISC_ADV_INT_MAX, advInt );
  }
